I have found a solution myself, but I'll wait until other people tell us which answer is better.

@users.find {|u| u.id == 50 }

Thanks for your answers!

If you want to do an ActiveRecord find you can do:

@users = User.find_by_id(50)

Or if you want to do an Array find you can do:

@users.find_all { |user| user.id == 50 }

Use detect:

user = @users.detect { |u| u.id == 50 }

Though there are ways to fetch just one record (with id 50) if you don't need the remaining 99.
